Initial analysis

The three-story, 6-unit multi-family residential building at 101 Alta St in Telegraph Hill, owned by Daniel Lorimer, has undergone significant renovations since its construction in 1900. The most substantial recent work occurred in 2013, when the basement floor was lowered by 2'-11", extended, and equipped with radiant heat systems throughout the building, with associated plumbing and electrical work totaling approximately $43,000. Earlier improvements between 2009-2011 included multiple bathroom and kitchen remodels, window replacements, and fire escape repairs following damage from a garbage truck. Several building violations were recorded and resolved between 2002-2010, primarily related to fire safety and structural issues, including problems with the fire escape, exterior doors, and unsafe stairs, though these were all abated by February 2010.

The building's maintenance history reveals recurring plumbing issues, including sewage leaks in 2007 and October 2009, and a significant complaint about severe mold, water leaks, and unsafe stairs filed in October 2009 that led to multiple permits for repairs. In 2016, there were complaints about unpermitted remodeling work in unit 1313, though these were quickly addressed. Recent external maintenance issues have included street cleaning, pavement defects, and graffiti removal as recorded in 311 calls between 2013-2024. Two fire incidents were recorded with no civilian injuries, one being a smoke scare and the other an unintentional alarm activation. The most recent significant building permit activity was completed in 2013, and there have been no major violations or complaints in the past 10+ years, suggesting improved maintenance and compliance in recent years.

Risk rating

How 101 Alta St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
37th percentile

Out of 684 buildings in this neighborhood, 431 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 37.7%
Moderate concern 12.0%
Severe concern 50.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
